- 1Kane Waselenchuk
Kane Waselenchuk has won 128 career International Racquetball Tour titles and 15 year-end #1 rankings, both records, and holds a career win-loss record of 651-62 across 23 seasons — a 91.3 percent win rate sustained over more than two decades of competition. At the peak of his dominance he strung together a 134-match unbeaten streak that lasted over three years, and through the 2019 US Open he had won 118 of the 172 IRT tournaments he entered, a 68.6 percent tournament win rate that dwarfs every other player in the sport's history. His career title total puts the next-closest player, Cliff Swain, at 71 IRT wins — meaning Waselenchuk has won nearly twice as many tournaments as the second-most successful player ever, a gap that has only widened as his career has extended into his 40s. His combination of a 91.3 percent career win rate and a title total nearly double the next-best player's has made Waselenchuk almost universally regarded as the greatest racquetball player of all time.

0 - 2Cliff Swain
Cliff Swain finished as the International Racquetball Tour's year-end number one six times — in 1990, 1993, 1994, 1995, 1998, and 2002 — a span of dominance stretching across more than a decade, and he won US Open titles in 1997 and 2001. During the 1993-94 season specifically, Swain won 13 of the tour's 19 stops, including two separate streaks of five consecutive tournament victories, a level of single-season dominance that remains one of the most statistically extreme stretches in the sport's history. He retired with 70 career IRT tournament titles, a total that stood as the sport's record until Kane Waselenchuk eventually surpassed it, and Swain was inducted into the USA Racquetball Hall of Fame in 2003. His combination of six year-end number one finishes and a then-record 70 career tournament titles has made Swain one of the most historically significant figures in American racquetball, second only to Waselenchuk in the sport's modern era.

0 - 3Paola Longoria
Paola Longoria has won six women's singles World Championships — in 2012, 2014, 2016, 2021, 2022, and 2024, most recently defeating Gabriela Martínez 11-5 in the San Antonio final — the most of any woman in the sport's history according to Guinness World Records. She also won four World Championship doubles titles partnered with Samantha Salas, in 2021 becoming the most decorated doubles pairing in the sport, and first won a Pan American Championship in 2006, the start of a run that made her the first Mexican woman ever to reach world number one. Longoria has now held that world number one ranking for well over a decade, sustaining her dominance across multiple generations of rising competitors from Mexico, the United States, and Latin America more broadly. Her combination of a record six singles World Championships and four doubles titles with Samantha Salas has made Longoria almost universally regarded as the greatest women's racquetball player in the sport's history.

0 - 4Rocky Carson
Rocky Carson holds the record for the most International Racquetball Federation World Championship singles titles with five — won in 2008, 2010, 2012, 2014, and 2016 — plus records for National Indoor singles titles (7) and National Doubles titles (10). He added 27 IRT tour titles across his career and finished as the tour's year-end number one twice, in 2007-08 and again a decade later in 2017-18, a gap that reflected his unusually sustained relevance against Kane Waselenchuk's prime-era dominance. Carson ranked in the IRT's top 10 for a record 23 consecutive seasons, a level of sustained top-tier competitiveness across changing eras of the professional game that few racquetball players have approached. His combination of a record five World Championship singles titles and his record 23 seasons ranked in the tour's top 10 has made Carson one of the most significant American racquetball players of the modern professional era.

0 - 5Michelle Key
Michelle Key, born in Phoenix in 1988, reached a career-high world ranking of seventh in 2014-15 and spent much of her career as one of the top American women chasing Paola Longoria's international dominance, reaching National Championship finals in singles (2016) and doubles (2013) without quite breaking through for the title in either. She won a Pan American Championship in mixed doubles partnered with Sam Bredenbeck, and added two Pan American Games medals with Team USA's women's squad — silver in Toronto in 2015 and bronze in Santiago in 2023. Key, now competing under the name Michelle Key Anderson, finally won her first National Singles title at the 2026 USA Racquetball National Indoors Championship, a breakthrough that came a full decade after her runner-up finish at the same event. Her combination of sustained top-10 world rankings across more than a decade and her eventual 2026 National Singles breakthrough has made Key one of the more persistent and ultimately rewarded careers in American women's racquetball.

0 - 6Sudsy Monchik
Sudsy Monchik won the US Open, racquetball's most prestigious tournament, four times — in 1996, 1998, 2000, and 2002 — making him and Kane Waselenchuk the only two men in the sport's history to win it more than twice. Before turning professional, Monchik built the greatest junior record in the sport's history, winning a national title in every single age division from 8 through 18, a sweep no other player has matched, and he later became the only player on record to win a national title or higher across five consecutive decades, from the 1980s through the 2020s. His 50-plus career tournament wins rank fourth all-time behind only Kane Waselenchuk, Cliff Swain, and Marty Hogan, and he won at least one pro tournament in each of his first eight seasons on tour, from 1993-94 through 2000-01. His combination of a four-time US Open championship and his unmatched five-decade national title streak has made Monchik one of the most significant American racquetball players in the sport's history.
